Zeuglonden,’ fol., 1849.—4. Teeth and vertebrz from Miocene beds 
at Eibergen and Swilbrock, in Guelderland, referred by me to the 
genus Zeuglodon, and subsequently described by Staring in his 
©“Bodem vom Nederland,’ vol. ii., p. 216, pl. ili—5. An almost 
entire skull from the Upper Miocene at Barie, Département de la 
Dréme, described by Professor Jourdan, in ‘Comptes Rendus de 
PAcadémie des Sciences,’ November 1861, and referred to Rhi- 
zoprion Bariensis, Jdn. The fore-end of the upper jaw of this 
specimen is described and figured by Professor Gervais, in the 
‘Bulletin de Académie Royale de Belgique,’ tom. xiii., No. 5, 1862. 
—6. Portion of cranium, a petrotympanic bone, a laniariform tooth, an 
atlas, and other vertebre of a large Zeuglodont, discovered by Ehrlich 
(1842) in the Molasse in the vicinity of Lintz, referred by H. von 
Meyer, in 1849, to Balenodon linteanus. Van Beneden figures, in 
pl. iv. of his memoir, the portion of the cranium as belonging to 
a Zeuglodont genus, which he calls Stenodon.*—7. Almost complete 
skulls of adult and young Zeuglodonts, with laniariform and serrated 
molar teeth, also discovered by Ehrlich at Lintz, in Upper Austria, 
and noticed by Klipstein, in Karsten and Decken’s ‘Archiv,’ 1842. 
Van Beneden gives a restored figure of the skull and dentition of 
this specimen in his pl. iii, and refers the species to Squalodon 
Ehrlichti, V. B. Two of the teeth, from Lintz, are figured by 
J. Miiller, op. cit., fol. xxiii., fig. 7. 
The chief part of M. Van Beneden’s work is devoted to the 
Zeuglodont fossils from the vicinity of Antwerp. The portions of 
skull enable him to describe the intermaxillaries which exclusively 
form the end of the rostrum, and are firmly and extensively united 
to each other: each intermaxillary bears three teeth, of which the 
foremost projects on the axis of the bone. Of the maxillary the 
author describes three portions ; the hindmost showing the convexity 
of the palatal portion, and the junction of the vomer. The man- 
dible is represented by various fragments, which indicate a long 
symphysis, extending as far back as to the two-rooted molars. The 
above-named portions of bone, and divers teeth, are all the parts on 
which the Squalodon Aniverpiensis, V. B., is fcunded. In the figure, 
pl. i., of this species, the skull is restored in outline from the 
specimens previously discovered at Lintz and Barie. 
The dentition is computed to consist of— 
Incisors, 3; canines, +; premolars, ~; molars, 7 = 13. 
This formula gives only the teeth of one side of the upper and 
lower jaws. 
The skull of the Zeuglodont from Lintz shows the massive 
character of the zygomatic arch, and the small size of the cranial 
cavity, which is widest behind. ‘The vomer is canaliculate supe- 
riorly. The posterior walls of the nasal passages are wanting ; 
* This name has been bespoken, in 1832, by Aredinet-Serville, in the ‘ Annales 
de la Societé Entomologique de France,’ for a genus of Cerambycini; also by 
Richards, in 1836, for a genus of Salmonide.—Appendix to Back’s ‘Narrative of 
Arctic Land Expeditions.’
